Application filed October 9, 1882. (N0 model.)

To all whom it may concern:

Be it known that I, HENRY WHEELER, a citizen of the United States, ofChambersville, in the county of Dade and State of Missouri, haveinvented certain new and useful Improve ments in SoclietWrenches; and Ido hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters of reference markedthereon, which form a part of this specification.

Figure 1 is a perspective view of the device. Fig. 2 is a face view ofthe ring. Fig. 3 is a transverse section taken through the grooves atthe end of the wrench, the ring being in elevation. Fig. 4 is a sideview, the ring being in section.

This invention relates to improvements in socket-wrenches; and itsobject is to furnish an adjustable wrench of this class which can bereadily adaptedto-differcnt sizes, and will be lirnily held at any pointof adjustment.

The invention consists in a wrench having thepeculiaritiesofconstruction hereinalterset forth.

in the annexed drawings, the letter A indicates the wrench. Extendingfrom and integral with the tang or stock a is onejaw, B, halved intowhich and held by a rivet, a, is the otherjaw, C. At each end of therivet is placed a washer, D, which bears against both jaws. At theirends b and c thesejaws are made on the inside with angular recesses bc,the two forming the socket of the wrench, for

shown. In use the ring is placed in the grooves E and F and the socketover the article, nuttap, &c., to be manipulated. lhe ring is turneduntil the proper notches catch thejoints e andf, when the spring G byits action locks the parts together. Power applied to the stock a by abrace or otherwise will then operate the wrench, moving the articlewhich it grasps.

The washers D perform an important function by bracing the jaws on .eachside, preventing any twisting action and weakening of thejoint.

Having described my invention, what Iclaim 1. The jaws B and 0, havingangular recesses b and c on the inside and points 6 and f on theoutside, in combination with the ring H, having notches h, as set forth.

2. Jaws B and O, in combination with the ring H and spring G, as setforth.

3. A socket-wrench having the following parts, to wit; the stock a, jawsB and 0, provided with angular recesses 11 and c, grooves E and F, andpoints 0 and f, spring G, and ring H, having notches It, as set forth.

In testimony that I claim the foregoing as my own I aftix my signaturein the presence of two witnesses.

HENRY WHEELER.
